<p><P>PROBLEM TO BE SOLVED: To provide a portable power supply apparatus that ensures higher safety. <P>SOLUTION: A portable power supply apparatus 10 having: a power input section connectable with an end of a power cable 11 having the other end connectable to a quick charge connector 53 of an electric vehicle 50; a DC/AC inverter 14 for DC/AC-converting and stepping down power transmitted from the electric vehicle via the power input section; and an AC 100 V outlet 15 for outputting the power DC/AC-converted and stepped down to the exterior. Further the portable power supply apparatus 10 includes: a voltage measuring unit 16 for measuring a reverse voltage reversing from the exterior to the inverter via the outlet; and an interface 19 for controlling the inverter on the basis of the reverse voltage measurement value measured by the voltage measuring unit. The interface is configured to operationally stop the inverter to stop the power output to the exterior when the reverse voltage measurement value is greater than 0 V. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
